vIMPROVEMENT IN THE CARRIERS OF BRAIDING-MACHINES.

To all whom it may concern.'

Be it known that I, OTIS E. D ROWN, of Pawtucket, in the county ofProvidence and State of Rhode Island, lia-ve invented a new and usefulImprovement in the Carriers of Braiding-Machines; and I do herebydeclare that the following is a full, clear, and exact description ofthesaine, reference being had to the accompanying drawings, making part ofthis specitcation, in which- Figure l is a side elevation of my improvedcarrier. Fig. 2 is a like View of the same with the teiision-weight andpawl in the position for delivering the yarn 'from the bobbin. Fig. 3 isa front elevation of the carrier. Fig. 4 is an elevation of the reverseside ot' the weight and pawl from that of 2, and Fig. 5 is a like viewot' a modified construction orn the same.

Similar letters of reference indicate corresponding parts in alll theligures.

My improvement belongs to that class of braiding-machines which have asingle serpeiitine race-plate for directing the movements of thecarriers, and are otherwise so constructed as to braid aside from thecenter of such plate as an essential condition to the braiding ot' wide,ilat braid; and the said improvement consists in the mode ofconstructing and arranging the tensionweight and the pawl that lets offthe yarn from the bobbin, andthe sepa rate guides upon which said weightand pawl slide, as hereinafter described, so as to reduce the height ofthe guide-post, for the purpose of preventing the carrier from bindingin the raceplate by the lateral strain produced by the tension of theyarn; and the said improvement further consists in the particular mannerliereinafter.described of reeving the yarn between the bobbin and thedelivery yarnguide at the top of the post to prevent unnecessaryabrasion of the yarn, and for the sake of greater convenience andexpedition in starting when an end or strand breaks.

The tension-weightD slides upon a dovetail guide, f, on the front sideof the vertical guidepost O, and the said weight is constructed as shortas possible, so that it may take up but little of the length of theguide, but is made broad and thick enough to make it sufficiently heavyfor its purpose, and it is constructed the guide-post and extendingdiagonally across the t'ront to the middle ofthe top ofthe weight, asshown in Figs. 2 and 3, for the reception and passage of the yarn underand around the weight in order to lift it by the bight of the yarn frombeneath and carry it to the extreme top of the guide-post, by means ot'which it will be seen that the remaining length of the guide-post may beexclusively employed for the traverse of the weight and be limitedaccordingly.

To facilitate this construction and arrangement the pawl F, instead ofbeing placed on the same guide above the weight as in the constructionpatented by Clemons, November 16, 1858, is placed on a separate dovetailslide, e, at the rear of the top ot the guide-post, as shown in Fig. el,so that the upper portion of the weight may slide past the pawl untilthe shoulder Z on the opposite side of the weight comes in contact withthe projection t on the pawl and lifts it from the ratchet in thebobbinlhead; or the pawl maybe constructed, as shown in Fig. 5, with ashank at right angles to it, and the separate guide may be formed bymaking the bobbin-spindle d hollow for the said shank to slide in andslotted at the upper end for the pawl E to project from and across thebobbin-head to the shoulder l on the tension-weiglit, by which it islifted to let olf the yarn.

The several parts being thus constructed and arranged, the height ot'the guide-post O may be reduced to that of the ordinary carrier patentedby Clemons, as above, while at the same time I am enabled to braid at anequal distance from the center, as upon the taller-carriers patented byJ. B. Wood, (No. 41,045,) withthis additional advantage, that by meansof the shorter carrier its running speed may be increased one-thirdwithout the liability of breaking the yarns that exists in thetaller-carrier mentioned, with, of course, a similar increase of theproduction of the machine over that of the tallercarriers and ltheirnecessarily slow speed.

rEhe mode of reeving the yarn is effected by means of two hooks, r ands,at the side of the guide-post, one, r, being, as usual, situated nearthe middle of the bobbin, and the other near the highest point to whichthe bottom of with a groove, t, at the bottom on one side of l theweight D ascends, and the peculiar construction of the weight D, with agroove and a hook, t, on the same side of the guide-post for the bightof the yarn to pass under the weight, as before described.

By means of this construction and arrangement the reeving of the yarn isrendered more convenient and expeditious, as it may be readily carriedunder the hook r and over the hook s, and then under the hook t, to formthe bight around the weight, and iinally through the delivery-guide fuat the top ofthe guide-post without removing the bobbin or other part ofthe carrier, and without any assisting implement, as is necessary in thecarriers above referred to.

Having described my improvement, I wish it understood that I am awarethat in the Clemons carrier above referred to the yarn is recved underthe tension-weight from a hole or guide through the guide-post, near themiddle of the bobbin, to the delivery-guide at the top; but in this casethe traverse ofthe weight is limited to the distance from the base ofthe carrier to the hole or guide through the guide-post, which must benear the middle of the bobbin, which traverse is whollyinsufficient forbraiding aside from the center, and can only be increased to the extentrequired by elevating the bobbin and the said yarnguide at its middleabove the base of the carrier, which so increases the length of carrierthat its running speed'has to be reduced to prevent the binding in therace-plate before mentioned and the consequent breaking of the yarn atfrequent intervals.

I am also aware that the arrangement of the pawl or latch to slide on aseparate guide is found in the carrier patented by J. B. Wood,- and isnot new but I am not aware of its having been used combined with oradapted to anyT method of rceving the yarn under the weight, wherebyadvantage would be gained by a skillful shortening er shaping of theweight, which would result in shortening the carrier in the manner andwith the beneficial results hereinbefore mentioned. [would not,therefore, be understood as claiming the separate arrangement of thepawl-guide independently of the combination herein set forth.

What I claim, and desire to secure by Letters Patent, is-

1. Combining the weight, constructed as described, to, be lifted fromthe bottom by the surrounding bight of the yarn, with the pawl,constructed as described, to slide on a separate guide, and permitting`the weight partially to pass -it before being lifted to let off moreyarn, substantially as described, for the purpose set forth.

2. The combination of r and s, as described, with constructed asdescribed, with the groove or hook t on one side of the bottom thereof,for reeving the yarn, substantially in the manner described, for thepurpose set forth.
